Ability to handle streams of data

[nsweeting]

Right now - I dont think this is supported.

I thought the recent introduction of the "frame" API could be used here - but I dont believe thats the case.

For context - we deal with large streams of data that need to be compressed to lz4. At the moment - we handle this via https://github.com/coherentpath/z_stream/blob/main/lib/z_stream/lz4.ex - which wraps https://github.com/rabbitmq/lz4-erlang. We have unfortunately had a bunch of build issues with newer versions of OTP which has become a bit of a blocker.

Is a stream based API doable?

Yes, a frame-based API is possible because the Rust crate we're using in nimble_lz4 supports it: https://docs.rs/lz4_flex/latest/lz4_flex/#example-compress-data-on-stdin-with-frame-format

Would you be willing to cook up a PR? 🙃
